Comcast xfinity wifi: how to enable port forwarding and

I keep trying to port forward via my TZ300 on my Xfinity home modem in bridge mode, but I can’t seem to get it to work. I’ve tried many times and followed the wizard’s directions, but I’ve never been able to get it to port forward. I contacted xfinity help, who stated that the bridge mode would not block ports, so maybe I’m doing something wrong? Is there a step-by-step for my configuration, which is different from the norm?
I found it out, so that’s healthy.
My xfinity modem was totally re-formatted and I had to start over.
I went through the process and discovered that in order for port forwarding to work, you must disable the firewalls by clicking the very small bottom check box that says disable it. Setting it to bridge mode, which is meant to disable the firewall as well, is apparently not the same thing. After that, you set it to bridge mode on both the IPv4 and IPv6 firewalls. Then, and only then, does it work as advertised. Thanks a lot to
I hate the SonicWall wizards because the names they produce are unhelpful when dealing with a large number of NATs and exceptions.
Please accept my apologies if this is a simple question, but when troubleshooting, I always find that starting with the basics is the best place to start.

My ultimate aim is to set up a VPN on my Cisco Router, which means getting rid of the Comcast Gateway. To that end, I’d like to logically shift my Cisco Router (and/or Switch) closer to the WAN and deactivate my Comcast Modem. I can’t really get rid of the modem because it offers WAN access, but I don’t need its DHCP, NAT, or firewall services. I’d like some help with setup.
With an inside address of 10.0.0.1/24, the modem serves as a DHCP server, NAT, and firewall. The WAN port of the router is connected to it with a dynamic IP address (DHCP client). On the LAN side of the router, it also has NAT (yes, double NAT’ed for now), DHCP Server, DNS, and NTP running.
The Comcast bridge isn’t completely transparent; the Modem maintains its IP address (10.0.0.1), which I can link to via http and reconfigure (thankfully) when I connect a laptop directly to Port 1 on the Modem. So, even if the Router doesn’t, my laptop knows how to deal with the Modem in bridge mode.

If you have the PS4 linked directly to a simple modem, you can never get open NAT. This is unlikely to be possible since none of your other devices would be able to connect to the Internet. The gateway you have may or may not function in the same way as a normal modem. There’s not much you can do about it except take Comcast’s word for it that all is fine. When a gaming console is linked to a router, I don’t believe I’ve ever seen “Free” NAT, because a router link can result in “Moderate NAT,” which is about the best you can hope for. I believe I could disable NAT entirely on the AirPort Extreme, but I am concerned that doing so would put all of the other devices on the network at risk. Just one computer on your network would be able to connect to the Internet if you “turn off” NAT on the AirPort Extreme. The remaining devices would be able to connect to the network, but not to the Internet. Furthermore, if you “turn off” NAT on the AirPort, your Default Host will vanish as well, since NAT must be allowed in order to use the Default Host settings.

The type of networking equipment that Comcast offers you is decided by a variety of factors. Although a standard DOCSIS cable modem will suffice for a simple Internet bundle, other services can necessitate the use of a modem capable of network address translation. Comcast may allocate you a router as well as a modem, or they may only send you a single gateway modem. In this case, you’ll need to open a port on your Comcast modem to allow your programs to communicate. Fortunately, all allocated gateway modems have a graphical user interface that makes it easy to open the port. Although the methods for performing this procedure are identical on each computer, there are significant variations in how to access the interface and make the required configurations. You must first obtain your internal Internet Protocol (IP) address before accessing the interface and opening the port for your specific brand or model.
Check the box next to “Allow Virtual Server.” In the “Private IP” area, type your local IP address, and then in the “Private” and “Public” port boxes, type the port you want to open. Pick the protocol type from the “Type” drop-down menu. Pick the “Both” option if you’re unsure.
